Specific embodiment
To be clearer and more comprehensible the utility model, hereby with preferred embodiment, and attached drawing is cooperated to be described in detail below.
As shown in Figure 1 to Figure 2, the machine for being adsorbed in spring of coil is utilized using traditional electricity loss brake for the utility model
Tool movement generates braking effect, devises disc type brake device structure in a kind of joint of robot mould group, including be set in motor
Hollow motor shaft 3 in rotor 8, the side of the rotor 8 is equipped with the breaker slot 6 being set in hollow motor shaft 3, described
Breaker slot 6 includes the restriction axis being set in outside hollow motor shaft 3 and the restriction face that 8 side of rotor is arranged in, the braking
